CLOSET TRAP FOR RAILWAY CABS.

Application filed April 9,

To all to hem it may concern:

I, Fonnns'r L. Score a citizen of the" contents when the car is running above av predetermined rate of speed. The present invention is an improvement over my railway closet trap disclosed in my application filed in the United States Patent Ofiice August 23, 1922, Serial No. 583,696.

The main object of this invention is to provide a railway closet trap comprising means whereby the trap will be automatically opened. quickly and locked in open position when the speed of the car reaches a pre-determined degree, and automatically closed quickly and locked in closed position when the speed of the car falls below said predetermined degree.

Other objects and advantages will appear hereinafter, and while I show herewith and will describe a preferred form of construc tion, I desire to be understood that I do not.

limit myself to such preferred form, but

that various changes and adaptations mayv be made therein without, departing from the spirit of my invention as hereinafter claimed. i

My objects are attained by the apparatus illustrated in the accompanying drawing, 40

in which:

Fig. 1 1s a sectlonal elevation taken through the longitudinal center of a rail-.

way car on which my invention is installed;

and Fig. 2 is a plan view of the operating lever of my trap.

Similar numerals refer to similar parts throughout both views. I

In the drawing 1 indicates the floor, of

a railway car and 2 a portion of the end of one of its trucks. A toilet bowl 3 of any suitable type is mounted upon the floor 1 within the car. The bowl. 3 discharges into a chute 4 which leads into a bottom dumping hopper 5 secured at its upper end to 1923. Serial No. 630,795.

the under side of the floor 1. The lower end of the hopper 5 is closed by an inclined doorG hinged at 7 to one side of said hopper ed an adjustable counter weight 11 for holdf ing the door 6 closed when the car is running below a predetermined speed or stand ing still, said weight being adjusted and held on said rod by a nut 12 screwing on said rod below the weight. An operating lever 13 is formed in two sections 14 and 15, pivoted together by ahorizontal pivot as at 16, and is formed. with forks 17 and 18 at its forward andrear'ends respectively,

the fork 17 lying in a horizontalplane .to straddle the hopper 5, and the .ends, of said fork beingpivoted at 19 to opposite sides of. said hopper with the lever 13extending rearwardly from the hopper, thus fulcruming the forward end of the lever 13 to said hopper. The door arm 9 and thesection 14% of lever 13 are pivotally connected to the 1 ends of a link 20 as at 21 and 22 respectively.

A flat spring 23 is pivoted at its lower end at 24 to the rear side of the hopper 5 and extends upwardly through the lever 01511 17 and carries a set screw 25 at its upper spring in theyrespective engagement of the sockets 26 and 27 formed therein, with a roller 28 journaled in the crotch'of fork end which engages the rear side of said." hopper for adjusting the tension of said 17 for respectively locking the door 6 in,

and 30 extend vertically from the lower and upper edgesrespectively of the lever section 14-, and a pair ofarms 31 and 32 extend vertically from the lower and upper edges respectively of the lever section- 15. A coil spring 33 is connected at its ends to the arms 29 and 31 respectively and a coil spring 34 is connected respectively at its H ends to the arms30 and 32.

A fly ball governor 35, which is driven by a bevel gear 36, is mounted on a hanger 37 suspended from the under side of the car floor 1. Ontheoperating collar 38 of said governor is a pin 39 which 'isengaged by the fork 18 of the lever 13. A short shaft- 40 is journaled in the lower part of hanger 37 on one end of which shaft is a bevel gear 41 in mesh with the bevel gear 36. A telescopic shaft 42 is connected at one end by universal joint 43 to the shaft 40 and at its other end by a universal joint 44 to one end of a shaft 45 journaled in bearings 46 and 47 on the car truck 2., On the other end of the shaft 45 is secured a bevel pinion car speeds up the governor swings the lever section 15 upwardly on'its pivot 16, against the tension of lower spring 33. When the speed of the car rises to a predetermined degree the governor raises the lever section 15 to such point as to place the spring 33 under suficient tension to swing lever section 14 upwardly and jump the roller 28 outof the socket 26 and into socket 27, so that the lever '13 straightening under the tension of said spring will through the link 20. quickly open the hopper door .6. When the speed of'the car falls below said predetermined degree the governor will swing the lever section 15 "downwardly against the tension of upper spring 34 until the tension of said spring is suflicient to swing the-lever section 14 downwardly and jump the roller 28 out of the socket 27 into the socket 26 so that the lever-13 through link 20 will close the hopper door 6.

Having thus described claim: I I

1. A railway closet trap including a hopmy invention I per adapted to receive the efflux from the closet, a door for said hopper, a lever, formed intwo sectlons pivoted together, a spring extending across the pivot of said sections and connected at its endsrespectively to said sections, a link connected to said door and toone of said sections, and means engaging the othersectlon for swinging said section against the tension of said spring so that said spring will swing the other section and open said door quickly when the speed of the car reaches a pre- 2. A railway closet trap including a hop- 'per adapted to receive the efliux from the closet, a door for said hopper, a lever formed in two sections pivoted together, a pair'of springs extending across the pivot of said sections and connected at their ends respectively to said sections, a link connected to said door and to one of said sections, and means engaging the other section for swinging said section against the tension of one of said springs, so that said spring-will open said door quickly when the speed of the car reaches a predetermined degree, and for swinging said section against the ten sion of theother spring so that said spring will close said door quickly when the speed of the car falls below said predetermined degree.

3. A railway closet trap including a hopper adapted to receive the efllux of the closet, a door for said hopper, a lever formed in two sections pivoted together, a pair of springs extending across the pivot of said sections and connected at their ends respectively to said sections, a link connected to said door and to one of said sections, aroller on saidsection, a flat spring formed with two sockets for respectively engaging saidroller, and means engaging the othersection for swinging said section against the tension of one of said pair of springs, so that said spring will swing the first section to jump said roller out of one socket into the other socket and open' said door quickly and lock said door open when the speed of the car reaches a predetermined degree, and for swinging said other section against the tension of the other of. said pair of springs, so that said spring will swing the first section to jump said roller out of the latter socket back into the first socket and close said door quickly and locksaid door closed when the speed of the car falls below said predetermined degree.
